How to check whether Google User's image is default or uploaded?

Question

How do I check whether user's profile picture is default or uploaded in Google?

Note: When you get user details from APIs.

Answer 1

Updating this answer for 2020: it's now possible to get the user's profile picture by sending a request to the people.get API with photos as the personFields to request.

You'll get back an array of images, and whenever default: true is present, it means it's a default (not user-set) image:

Example (if you're using this with OAuth):

GET https://people.googleapis.com/v1/people/me

Sample response (with profile picture)

{
  "resourceName": "people/117055959617985617271",
  "etag": "%EgQBAzcuGgQBAgUHIgxHamp6MG9wZ3hOcz0=",
  "photos": [
    {
      "metadata": {
        "primary": true,
        "source": {
          "type": "PROFILE",
          "id": "117055959617985617271"
        }
      },
      "url": "https://lh3.googleusercontent.com/a-/AOh14Gg_-udXd3O6K1URTBTEK2rLa2DOh6G2dgmOHcOBOtE=s100"
    },
    {
      "metadata": {
        "source": {
          "type": "CONTACT",
          "id": "2"
        }
      },
      "url": "https://lh3.googleusercontent.com/a/default-user=s100",
      "default": true
    }
  ]
}

Sample response (default only)

{
  "resourceName": "people/113009277022343767972",
  "etag": "%EgQBAzcuGgQBAgUHIgxxdHVTY3IxZVJIUT0=",
  "photos": [
    {
      "metadata": {
        "primary": true,
        "source": {
          "type": "PROFILE",
          "id": "113009277022343767972"
        }
      },
      "url": "https://lh6.googleusercontent.com/-6NS3awoYRXw/AAAAAAAAAAI/AAAAAAAAAAA/AMZuucnTo-mElIpcAEazDV9DAs1VyYDEIw/s100/photo.jpg",
      "default": true
    }
  ]
}

Answer 2

people.get includes a isDefault value in the image object. E.g. if you try it for +Google you will get;

"image": {
    "url": "https://lh4.googleusercontent.com/-v0soe-ievYE/AAAAAAAAAAI/AAAAAAACyas/yR1_yhwBcBA/photo.jpg?sz=50",
    "isDefault": false
}
